Hi Henk,

The advantage that cyanotype offers over a blue gum image is the increased
print density and sharpness. It provides a good base to print multiple gum
layers over. Cyanotype/gum is a great combination for certain images that
benefit from sharpness in detail and/or a rich blue/green/purple emphasis.

Other subjects work better as straight gum prints. I can't say I like one
method more than the other. They both work well, it depends on the
photograph.

It takes 5 or more coatings to get a noticeable shine in the shadows when
I'm printing gum. It's a nice effect but it sure is easy to overdo it and
kill a print from too-heavy printing.

We're sitting out the season's first snow storm with high winds and wet
snow. It's another beautiful day in Wyoming.

Here's a photo of my latest acquisition, a 1962 Willys pickup:

Dave Rose
